Thetford Pumpout Nozzle & Adapter
When it comes to emptying an RV or portable waste tank cleanly, the connection between the tank and the hose is where things succeed or fail. Thetford has spent decades building mobile sanitation equipment, so its pumpout nozzles and adapters are designed to work as part of a complete waste-handling setup rather than as stand-alone fittings. This page focuses on that narrow but important slice of the lineup.
Built Around Thetford Waste Systems
Thetford was founded in 1963 in Michigan and is credited with inventing the Porta Potti in 1968 and the cassette toilet in 1988. That heritage matters here: its nozzles and adapters are engineered to mate with the company's own tanks and macerator hardware, which takes much of the guesswork out of fitment.
A good example is the Sani-Con nozzle with cap. It is made for the Sani-Con macerator waste dump system, and the drip cap on the outlet end allows clean, no-drip storage when the nozzle is installed. The nozzle is designed to fit most sewer pipes and provide a gas-tight seal. Its threads are male on both ends, which helps prevent a drinking water hose from being hooked to the sewer nozzle by mistake, a small but meaningful safety detail.
Adapters for Portable Tanks and Sewer Hoses
Thetford also makes termination adapters for its SmartTote portable waste tanks. The SmartTote adapter is a 3-inch bayonet-style double pin connector that lets you attach a sewer hose to a premium roll-away tote for transfer to a dump station. Bayonet-style fittings are common across RV sanitation, so it pays to match the connector type to your tank outlet before ordering.
Related Thetford fittings include a bumper hose adapter designed to fit a standard 4-inch trailer hose bumper, allowing convenient storage while attached to a 3-inch sewer hose. These accessories round out the hose-handling side of the system.
What to Check Before You Choose
- System compatibility: Confirm whether you are working with a Sani-Con macerator, a SmartTote tank, or a standard gravity-drain outlet.
- Connection type: Bayonet, threaded and bumper-style fittings are not interchangeable without the right adapter.
- Hose diameter: Many RV sewer hoses are 3 inches, but verify against your outlet and storage hardware.
- Seal quality: A gas-tight, leak-resistant seal protects both hygiene and your equipment during pumpout.
